The original purpose of the per-superblock d_anon list was to
keep disconnected dentries in the cache between consecutive
requests to the NFS server. Dentries can be disconnected if
a client holds a file open and repeatedly performs IO on it,
and if the server drops the dentry, whether due to memory
pressure, server restart, or "echo 3 > /proc/sys/vm/drop_caches".
This purpose was thwarted by commit 75a6f82a0d10 ("freeing unlinked
file indefinitely delayed") which caused disconnected dentries
to be freed as soon as their refcount reached zero.
This means that, when a dentry being used by nfsd gets disconnected, a
new one needs to be allocated for every request (unless requests
overlap). As the dentry has no name, no parent, and no children,
there is little of value to cache. As small memory allocations are
typically fast (from per-cpu free lists) this likely has little cost.
This means that the original purpose of s_anon is no longer relevant:
there is no longer any need to keep disconnected dentries on a list so
they appear to be hashed.
However, s_anon now has a new use. When you mount an NFS filesystem,
the dentry stored in s_root is just a placebo. The "real" root dentry
is allocated using d_obtain_root() and so it kept on the s_anon list.
I don't know the reason for this, but suspect it related to NFSv4
where a mount of "server:/some/path" require NFS to look up the root
filehandle on the server, then walk down "/some" and "/path" to get
the filehandle to mount.
Whatever the reason, NFS depends on the s_anon list and on
shrink_dcache_for_umount() pruning all dentries on this list. So we
cannot simply remove s_anon.
We could just leave the code unchanged, but apart from that being
potentially confusing, the (unfair) bit-spin-lock which protects
s_anon can become a bottle neck when lots of disconnected dentries are
being created.
So this patch renames s_anon to s_roots, and stops storing
disconnected dentries on the list. Only dentries obtained with
d_obtain_root() are now stored on this list. There are many fewer of
these (only NFS and NILFS2 use the call, and only during filesystem
mount) so contention on the bit-lock will not be a problem.
Possibly an alternate solution should be found for NFS and NILFS2, but
that would require understanding their needs first.

With PTI enabled, the LDT must be mapped in the usermode tables somewhere.
The LDT is per process, i.e. per mm.
An earlier approach mapped the LDT on context switch into a fixmap area,
but that's a big overhead and exhausted the fixmap space when NR_CPUS got
big.
Take advantage of the fact that there is an address space hole which
provides a completely unused pgd. Use this pgd to manage per-mm LDT
mappings.
This has a down side: the LDT isn't (currently) randomized, and an attack
that can write the LDT is instant root due to call gates (thanks, AMD, for
leaving call gates in AMD64 but designing them wrong so they're only useful
for exploits). This can be mitigated by making the LDT read-only or
randomizing the mapping, either of which is strightforward on top of this
patch.
This will significantly slow down LDT users, but that shouldn't matter for
important workloads -- the LDT is only used by DOSEMU(2), Wine, and very
old libc implementations.

Pull x86 PTI preparatory patches from Thomas Gleixner:
"Todays Advent calendar window contains twentyfour easy to digest
patches. The original plan was to have twenty three matching the date,
but a late fixup made that moot.
- Move the cpu_entry_area mapping out of the fixmap into a separate
address space. That's necessary because the fixmap becomes too big
with NRCPUS=8192 and this caused already subtle and hard to
diagnose failures.
The top most patch is fresh from today and cures a brain slip of
that tall grumpy german greybeard, who ignored the intricacies of
32bit wraparounds.
- Limit the number of CPUs on 32bit to 64. That's insane big already,
but at least it's small enough to prevent address space issues with
the cpu_entry_area map, which have been observed and debugged with
the fixmap code
- A few TLB flush fixes in various places plus documentation which of
the TLB functions should be used for what.
- Rename the SYSENTER stack to CPU_ENTRY_AREA stack as it is used for
more than sysenter now and keeping the name makes backtraces
confusing.
- Prevent LDT inheritance on exec() by moving it to arch_dup_mmap(),
which is only invoked on fork().
- Make vysycall more robust.
- A few fixes and cleanups of the debug_pagetables code. Check
PAGE_PRESENT instead of checking the PTE for 0 and a cleanup of the
C89 initialization of the address hint array which already was out
of sync with the index enums.
- Move the ESPFIX init to a different place to prepare for PTI.
- Several code moves with no functional change to make PTI
integration simpler and header files less convoluted.
- Documentation fixes and clarifications"

for the type-c phys. The Kevin Chromebooks based on rk3399 now can use their
internal edp displays. RK3328 gets its efuse node and Mali450 gpu node,
which actually produces already some nice results with the WIP Lima driver.

Merge tag 'v4.16-rockchip-dts64-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into next/dt
Pull "Rockchip dts64 changes for 4.16" from Heiko Stübner:
General RK3399 gets Mipi nodes, fixes for usb3 support and better support
for the type-c phys. The Kevin Chromebooks based on rk3399 now can use their
internal edp displays. RK3328 gets its efuse node and Mali450 gpu node,
which actually produces already some nice results with the WIP Lima driver.

There are several places within the Kernel tree with nested
structs/unions, like this one:
struct ingenic_cgu_clk_info {
const char *name;
enum {
CGU_CLK_NONE = 0,
CGU_CLK_EXT = BIT(0),
CGU_CLK_PLL = BIT(1),
CGU_CLK_GATE = BIT(2),
CGU_CLK_MUX = BIT(3),
CGU_CLK_MUX_GLITCHFREE = BIT(4),
CGU_CLK_DIV = BIT(5),
CGU_CLK_FIXDIV = BIT(6),
CGU_CLK_CUSTOM = BIT(7),
} type;
int parents[4];
union {
struct ingenic_cgu_pll_info pll;
struct {
struct ingenic_cgu_gate_info gate;
struct ingenic_cgu_mux_info mux;
struct ingenic_cgu_div_info div;
struct ingenic_cgu_fixdiv_info fixdiv;
};
struct ingenic_cgu_custom_info custom;
};
};
Currently, such struct is documented as:
**Definition**
::
struct ingenic_cgu_clk_info {
const char * name;
};
**Members**
``name``
name of the clock
With is obvioulsy wrong. It also generates an error:
drivers/clk/ingenic/cgu.h:169: warning: No description found for parameter 'enum'
However, there's nothing wrong with this kernel-doc markup: everything
is documented there.
It makes sense to document all fields there. So, add a
way for the core to parse those structs.
With this patch, all documented fields will properly generate
documentation.

Everything there is already described at
Documentation/doc-guide/kernel-doc.rst. So, there's no reason why
to keep it anymore.

kernel-doc-nano-HOWTO.txt has a chapter about man pages
production. While we don't have a working "make manpages"
target, add it.

There is a mess on this chapter: it suggests that even
enums and unions should be documented with "struct". That's
not the way it should be ;-)
Fix it and move it to happen earlier.
